Not so nice 
Crankshaft suitable for mopeds / mopeds with Sachs 50/2 & 50/3 engines.
Difference to the Sachs 3-/4-speed crankshaft: The diameter of the cheek journals is smaller (E15 bearings must be used).
The crankshaft can also be used on Sachs 503 engines, so that the drive wheel does not rub against the housing, this must be underlaid with 1.5 mm spacers. You can find the appropriate spacers in the accessories section.
Mäsig-läsig! – We strive to offer you the widest range of moped spare parts. However, this product is of rather poor quality and is not recommended by us. Should you nevertheless choose this item, we can understand your decision, but cannot offer you any guarantee or exchange.
The connecting rod bearing may be too rough, which can lead to the lubricating film breaking off. This in turn can cause the connecting rod bearing to run hot.
High-quality alternatives such as our swiing crankshaft can be found in the accessories section.
